 — Cellula rotunda ex zoospora formata germiuando undique fila- 

 nionta mycelica matrice dein immersa, emitteus; cellula formata 

 in zoosporangium se mutans. Dum sporangia perdurantia rorman- 

 tur, dute cellula^ copulantur, et protoplasma alterius in alterani ei"- 

 lunditur. Ex copulatione sporangium perdurans, membrana crassa 

 circumdatum, oritur.
